PORTABLE PEN FOR ANIMALS.

SPECIFICATION forming part of Letters Patent No. 418,313, dated December 31, 1889.

Application led April l2, 1889. Serial No. 306,927. (No model).

To a/ZZ whom t may concern:

Be it known that I, DAVID DUGKWORTH, a citizen of the United States, residing at New Lisbon,in the county of Juneau and State of Wisconsin, have invented1 certain new and useful Improvements in Portable Pelis for Animals; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use-h t-he same, reference being 'had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. u

This invention relates to certain new and useful improvements in portable pastures or pens for pigs, sheep, and other animals; and it has for its object to generally improve upon the construction of this class' of devices, and to provide a simple, cheaply-constructed, and durable inclosure so constructed as to admit of its being readily moved from place to place when desired, and when in position will rest securely upon the ground.

To these ends, and to such others as the invention may pertain, the same consists in the peculiar combinations and in the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and thenispeciiically defined in the appended claims. l

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, like letters of reference indicating the same parts throughout the several views, and in which drawings* Figure l is a perspective view of a portable pasture constructed in accordance with my invention. Fig. 2 is aside view of tl1e/same,in which view the pasture is shown/as raised upon its wheels and in readiness/for moving Reference now being had to the details of the drawings by letter, A designates the fence or walls of the inclosure, which maybe of any convenient or desirable size, and is preferably rectangular in form. The fence is made in the usual form, and consists of a series of uprights B, to which are nailed or otherwise suitably secured the rails or boards C. One of the end sections, as D, is provided with a gate, and in the present instance I have shown the entire end of the pasture as hinged at one of its ends to one of the corner posts or uprights Vand its opposite end provided with suitable hooks adapted to engage staples in the outer face of the opposite cornerpost, thus forming a suitable and convenient gate to the inclosure.

E and E2 are uprights arranged upon opposite sides of the inclosure ata point substantially in its longitudinal center. These uprights are secured to the side rails of the fence and are provided with diagonal braces F, extending from the tops of the said uprights to the next adjacent posts or uprights of the fence upon either side. While the principal office of these braces is to strengthen the struct-ure, it is at once evident that they serve as rafters to support a roof, as shown in Fig. 2, to protect the animals from the sun or from the effects of storms.`

G is a transverse shaft suitably journaled near its ends in openings formed for the purpose within the uprights E and E2, and having secured to its extreme ends, which project a short distance beyond the outer face of the inclosure, bell-crank arms or levers H,`

J is a lever pivoted at a point between its n ends, as at a4, to one of the sides of the inclosure, and having pivotal connection at its lower end with the free end of. the link H2. It will be readily 4seen that by this construction the shaft G may be turned by simply moving the operating-lever J, and that by such revolution of the shaft the wheels I may be raised or lowered as desired.

In order to secure the wheels in their adj usted position, a locking-pin h, adapted to be fitted within holes b in the upper rail of the fence, is provided.

J is a truck of ordinary construction, provided with wheels J 2 and pole or handle J3, and K is an upright rising from the axle of said truck ata point between the wheels. The upper portion of the upright K is bifurcated, as shown, and within this bifurcation is pivotally attached one end of the bar or IOO - timber K2, the Opposite end of which bar is securely lattached to the timber K3-Within the inclosure.

L is a timber, one end of which is secured to one of Ithe posts or uprights of the end of the inclosure, While its free end is passed through the bifurcated portion ofthe upright K, and is provided with a series of holes d. By this construction it Will be readily understood that the wheels of the truck J may be readily raised fromlthe ground or lowered by" simply swinging the lower end of thestandard K, Which is attached to the axle of the truck, backward or forward, and 'the said wheels will beheld in their adj usted position' by'isimply passing a locking-pin d through oneof the holes' d in the timber L. I

Theoperation vis simple andwill `be readily` understood from theforegoingf description.V

The structure maybe greatly stren,g ;thenedl by`fthe'faddition'-of 'diagonal brace-rods vM,f whiclif'f are l Aprovided with suitable turml buckles M2 for regulating thetension of lthe-- rod'ysyasis 'common in constructionsaof'this character. r

Having thusdeseribedmy invention, what 1 I claim to be new, and desire to secure by Letters Patent, isV

1. The combination, with the fence constituting the inclosure, of the transverse shaft G, the bell-crank levers H H2 on said shaft and carrying stub-axles, the wheels on said stub-axles, and thel lever J, pivoted to said fence and pivotally connected at one end to one endof one of the arms of one of the bellcrank levers, substantially as and for the npurpose specified.

. 2. The-combination,Withthe fence constituting the inclosure, and the vertically-adjustable Wheels I; forsupporting said fence, of the longitudinal timber K2, the bifurcated upright K, pivotal-ly connected to theforwarduf purposefspecified.-
